' INSULATOR-SUPPORTNG- FIXTURE.

Appiiaiian fiiefi May 4. 1

To all idiomy it may com n Be it known that I, @Hann-ns li. Pinnen, Jr., a citizen. of the United States/and a resident of Pittsburgh, in the county ot' Allegheny andv Stateful1 Pennsyl vania .have invented certain new and useful linproveineiits in lnsiilator-Supportiiigi Fixtures, ot which the Jfollowing is'a specilicatioiii My invention relates to insulator supporting iixtures and involves improved construction. v The purpose ot the invention is to provide a strong, inexpensive fixture particularly adaptable 'tor siu'iporting` the conductors oi hig'hteiision circuits and which can be readily secured in place.y as for example on a pole, with a minimum of labor and expense and Without the need of gaining the pole.

lclore in detail, the invention contemplates the construction of fixtures of pipe lengths rigidly secured together by strong;` `cid durable castings which are curved to accurately lit the surface of the supporting pole.

The various features ot the 'invention are clearly shown on the aecoinpanying drawing in which Figure 1 is an elevational view ot' one of iiiy iiiiproved fixtures and one end Iol the -pole to which the fixture4 is secured7 and Fig. 2 vis a. top View of the Fixture and pole.

The fixture shown comprises a, body part 5 in the torni oli a length of ordinary wroug'l'it iron pipe 'whose lower. section (i is bent into a halt circle to bring 'the end 7 into parallelism with the inain part of the body.r At intermediate points of the body are side brackets 8 and l) each formed by giving' the end of aY piece or' ordinary pipe a quarter bend, the inner ends of the pipe being secured to the body by means of suitable castings 10 and l1. the brackets being so secured that their outer ends 8 and 9 are parallel with 'the body and the bracket-s are preferably in die same plane with the curved end G of the body. The ends 7, S and 9 are preferably tapered by 'forging in -order t0 receive suitable tliiinbles 1Q for ends couldbe threaded to directly receive insulators, or threaded to receive the tliiinibles'ceinented into insulators.

The castings i0 and 1l. are preferably so Specification of Letters Patent.

spaced that the insulator supporting' ends ot (he brackets and the insulators l received thereby ivill be eqiudistant. in the particie lar ari'anggjeiiient shown the insulai'injsup-6e .body 5 extends through the sleeves oli the 70 castings ivhilc the inner ends of b racketsaS and J extend into the lateral sleeve li ol the `lower and upper castings respectively. As shown, the body 5 is secured to the castingsI by pins 16. i into the lateral sleeves oi' may also bevsccured by iiieaiis ol pins lll. rllie inner fares of the bases lil ot' the castings are prefer-i ablyv con iaved to lit the sur'lacekoi'l the "pole T he brackets may be threaded '75 p to which the fixture is secured, and

orde-r to rigidly secure the fixture boltllioles li' are provided through the castings'iind the body 5 has registering;Y bolt holes for re! ceiving bolts 1S which prete ibly' extend'eiif tirely through they hole. Such b'oltsfto- 35 gether with the concave bases otthe rasfiiiejs will securely and 'rigidly-hold-thetiy ture to 'the pole without need yof ciit'liiiffn grains in the pole. rlllic lixture may of c" `irs be secured to the pole at any point. i However. in liifih tension service `work it is de si rable to provide a `guard wire and or'tbis purpose lY have shown the upper end 5" o i"'\ the body 5 extended a distance above the upper bracket and I provide a 'suitable 95 clamp 'i9 'lioixsecuriiig the guard Wire tothe tixture. Where the fixture isthiisextended tor receiving;` a guard Wire, it is preferably secured to the pole near the upper eiid`- .thereot as shown. in order that/fthe? 'g/uard l ivire will clear the pole.

lVith the above constructii'in a very strong and durable lixture is produced,` the body 5 being' continued through' and rigidly cured to the castings to forni a rigid support.

This will combination of a body par-t in the if'oiin of' a single length of inetal bent upwardly at'its lower end to form an insulator supporting bracket, fittings secured to the body and 'spaced above the lower bent end thereof,

and side brackets secured to and extending from said fittings, said fittings being adapted to be secured directly to a support to thereby support the fixture.

2. An insulator supporting fixture coinprising a. straight vertical body part whose lower end is gradually bent upwardly to form an insulator supporting bracket, a side bracket secured to and extending froin the body part above the lowerbracket thereon, and another side bracket extending from the body part at the point between said other brackets but in the opposite direction, insulator supporting means at the ends of the brackets and said insulator supporting means being equidistantly apart.
